Recently, there are debates about complex systems which consist of many complex systems and their relations. As the relations between complex systems become in- tense, the whole complex system can be represented as a overlapping of many complex systems, and understanding this superimposing characteristics become also important to address the whole system’s characteristics. Integration and decomposition of complex system differ from the systems’ characteristics. Therefore different strategy is needed to understand diverse systems.
In this thesis, we address several superimposed complex systems, and suggest a framework of superimposed complex systems using complex network theory with abstraction of complex systems in a view of relationship. We introduce a concept of multiplex system composed of superimposed networks. With the superimposed network concept, network categorization is proposed based on the strength of overlapping and interference. We investigate the difference of network characteristics along the category, and discuss the difference in research approaches by categories. Based on categories, we also suggest the methodologies considering properties arising from system overlapping.
With the methods, we found diverse complex system properties from social and brain systems. In general, we suggest that the different strategies are required in accordance with the systems’ superimposition characteristics, and important network properties such as distance also differ from the superimposition characteristics of each individual system.
